Once again…..thank you for the response. I always learn something from this site, especially in my short tenure. I am getting a better understanding/handle on these engines and hope to keep them in the 10,000 hr category.

Thanks again.

How do we feel about fuel additive (injector cleaner)? Might this help with soot problem or are they all just snake oil?

Thank you very much!

Thank you both for the reply. Clark, my engines are 175 hp, 6 cylinder (N/A).

I usually run them at 1850 rpm (8 kts). I can accept the nature of the beast and will continue to monitor. Love my Hinos and will maintain them.

Any problem running them at my posted RPM? I run them up hard at the end of a trip to, what I think is ‘cleaning’ them out (or what my dad used to say in his old car; “just cleaning out the carbon”).

Thank you both again!
